TRACY V. BUGKWALTEB, OF ALTOONA, PENNSYLVANIA.

MOTOR-VEHICLE.

Specification of Letters Patent.

Patented Sept. 18, 1917.

Application filed January 10, 1917. Serial No. 141.516.

1 '0 ah whom it may concern Be it known that I, TRACY V. Boon- WALTER, a citizen of the United States, residin at Altoona, .in the county of Blair and btate of Pennsylvania, have invented certain Improvements in Motor-Vehicles, of which the following is a specification.

This invention relates more particularly to vehicle frames for use in various Ways, but it is designed primarily for use in cars that are self propelled on rails, particularly gasolene section cars.

A chief object of my invention is to provide a strong, convenient and efiicient motor driven section car with improved means for eflecting its convenient removal from the track, preventing injury to the mechanism when the wheels are oil the rails, stop ing the car automatically when it has een thrown oil the track while running, and protecting the workmen carried from injury by operating mechanism.

A leading feature of my improvements is found in the end truss constructions which covcr the wheels and extend laterally beyond the rails and downward approxi' inatcly thereto, or so as to have a clearance less than the height of the rails, these trusses being adapted for supporting the car platforms over the wheels and longitudinal iool hoards exterior thereto.

'lhc wheels, together with the driving incchanism. are housed by the parts of my improvements. and the car is carried thereby on the rails when the wheels have been intentionally removed or have accidentally left the track. The car will he stopped by friction between the frame and tho rails when it has left the track while running and can hr skidded on the rails and removed tiicrei'rom readily when desired.

The characteristic advantages of the imn-ov( -ments will he more fully understood from the following descri 'ation of a special 'onstruction embodying the same and the accompanying drawings in illustration thereof.

In the drawings. Figure l. is a plan view of a car embodying improvei'nents of my invention. with the upper deck member removed: Fig. 2 is a side elevation of the car; Fig. 3 is an end clevatiou of the sameconstruction mounted on rails. and Fig. 4 is a broken end elevation of the car ofi' the track and supported by the engagement of the end trusses with the rails.

The car illustrated in the drawings is provided with a frame comprisin the longitudinal outer sills 1 and inner Si] 5 1 having the form of channel bars, the cross-bars 2 of tubular form fixed on the ends of the sills by elevises 3, the truss struts 41 having the form of angle bars with top extensions 4' fixed to the ends of the sills, the top and bottom truss chords 5 and 6 having the form of angular bars fixed to the suspended uprights 4,,the diagonal cross braces 7 onnecting the top and bottom chords be en the uprights, the diagonal braces 8 having the form of angle bars connecting the end members 4 and the ends of the top chords 5 with the ends of the bottom chords (5, the longitudinal plates or boards 9 fixed to the members 6 and 8 withfihe aid of the bearings 9, and the longitudinal running boards 10 having'their ends fixed outer end. of the members (3.

Struts 1, having the form of angle irons, are fixed at their lower ends to the sills 1, longitudinal sills 12 are fixed to the tops of these struts, cross pieces 13 connect the sills, and guards 14 are fixed to the end struts 11 and the cross-beams 13 Journal hearings 0; boxes 15, for the axles 16 having the \vl els l7 thereon, s11)- port the springs 18 by zhich the sills 1, directly, and the frame are supported. Radius or tie rods 19 and 20 connect the boxes for the respective axles to the sills 1' and end truss members 4, and links 21 connected with the'sills 1 pass around the tie rods to limit the upward movement of the frame.

It will he understood that the frame de scribed is adapted to be boarded over to provide platforms for carrying men or materials and a housing for relatively movable parts described (all of which lie within the frame) as well as for the braking parts comprising the shoes 22, the operating rods 23 and the retracting springs 24, and the propelling parts comprising the driven sprocket wheel 25 on the axle 16, the, sprocket chain 26 which drives the wheel 25, the sprocket wheel 27 which is fixed on the journaled shaft '28 and drives the. chain 26, L. .a motor 29 for driving the shaft 28, the fuel tank 30 for supplying the motor, the system 31 for cooling the water, the exhaust mechanism 32, and the compressor I|l('1 $lIrH if;-;. :34 and the various connections thereof.

to the The. distance between the bottoms of the end trusses, or'the chords (3, and the rails :31, is less than the height of these rails. 'l'beret'ore when the wheels have been remored from or have left the rails, the car can be carried by the engapmnent of the bottom chords with the rails withoutthe wheels contacting with the hes or ballast. and the trusses ot' the derailed ear will ride. on the rails to stop the car by friction, or can he slid on the rails to remove the car from the track.

Haring described'my ipven ion, I claim:

1. In a car, the combinat an with means comprising traction wheels and. journal boxes therefor, of a frame having depending end trusses extending beyond said wheels and between which said wheels are disposed, said trusses havim 'lmttom members whereby said car can ie skidded and means for tyin together a truss and journal box aforesaid.

2. In a car, the combination with traction wheels, of means carried by said wheels, said means comprising a frame having depending trusses extending laterally of said ear beyond said wheels and running boards extending along said car exterior to said wheels and supported by said trusses.

3. In a car, the combination with traction wheels. of housing means comprising depending end trusses extending aterally of said ear, side foot boards and a superstructure.

4. In a car, the eon'ibination of carrying and housing means comprising end trusses, side boards, side platforms, and an elevated platform between said side platforms proriding a housing for motor mechanism for driving said ear,-0f traction wheels operable by said motor mechanism and protected by said trusses, boards and side platforms.

In testimony whereof I have hereunto t my name this 3th day of January, 1917.

TRACY V. BUCKWALTER.
